Mixproof valves
Low cost of ownership
Alfa Laval mixproof valves
are designed to provide the
lowest possible operating
costs throughout their
exceptional service life.
This key advantage comes
from a combination of low
maintenance costs, using
fewer utilities, fewer seals
in product wetted areas,
easy repair and reduced
spare parts inventory. It
also comes from minimizing
downtime and any resultant
loss of earnings.
Efficiency and sustainability
Engineered with the latest effi-
ciency and sustainability princi-
ples in mind, Alfa Laval mixproof
valves feature fast-acting,
efficient actuators. The actuator­
requires a smaller volume of
air to execute seat lift and seat
push, which results in low air
consumption and minimal loss
of Cleaning-in-Place (CIP) fluid.
The valve seat, designed with
throttling edges during seat
lift and seat push, accelerates
cleaning fluid to improve CIP
efficiency and minimizes the
amount of CIP fluid used.
Alfa Laval supplies several different designs of mixproof valves, all with leakage
detection, which helps boost reliability and safety levels.
With its modular design, the new Alfa Laval Unique Mixproof CP-3 Valve delivers
optimum hygiene and legendary performance. Capable of being customized
to meet various process demands, this valve joins the only complete line of
products for the dairy industry that meets 3-A Sanitary Standards and

Valve control
and monitoring
One of the most effective ways to reap full benefit from high-quality hygienic
valves is to control and monitor their action as accurately, reliably and
economically as possible. Alfa Laval provides a full range of easy-to-install,
easy-to-use valve-top control and monitoring indicator units for use with
hygienic valves.
More reliable, cost-effective control
Traditional indicators are rarely capable of main­
taining pre-set parameters for valve operation.
Alfa Laval units solve this by using a state-of-the-
art, no-touch sensor system, pre-configured with a
tolerance band. This does away with adjustments
during the unit’s service life, providing you with
a time-saving, set-and-forget solution that also
keeps production downtime to a minimum.
Cost-effective combinations of Alfa Laval
ThinkTop®
top-mounted automated control head
for pneumatic valves and Alfa Laval IndiTop valve
position indicators give you full control over fluid
handling processes – with the exact degree of
automation­you require.
Easy to install
These units fit onto all Alfa Laval hygienic
valves fitted with actuator valve-tops in
an easy, straight­forward procedure
that requires no special expertise or
costly adaptors. This makes them
ideal for retrofitting and updat-
ing your existing processing
plant and for increasing
flexibility. Once fitted, the
initial set-up is done
manually using a fast
and foolproof “five-
push setup”.
Alfa Laval valve-top control and indicator units
benefit your operations by ensuring:
• Better control and monitoring of processing
operations
• Full insight and documentation about actual
events
• Greater safety and reliability
• Low cost of ownership due to savings on
time and manpower and elimination of
downtime and errors
• Easy upgrading, expansion and
reconfiguration of existing instal-
lations, with no adaptors
required.

Low cost of ownership
Alfa Laval control and indicator units
give you a remarkably low cost of
ownership via savings on time, man­
power and installation costs, as well
as by boosting production uptime
throughout the service life of the unit.
ThinkTop and IndiTop units feature
modular, fully encapsulated (potted)
designs that are extremely robust
and have only a small number of
components. This saves on spare
parts inventory and maintenance
costs throughout their service life.
Built to last
Alfa Laval control and indicator units
are built for maximum durability, pro-
viding long-term service both indoors
and outdoors. They comply with the
stringent NEMA 4/4X, IP66 and IP67
standards for protecting electronic
equipment against penetration by
dust particles or liquids.
ThinkTop automated control heads
for pneumatic valves are completely
watertight and suitable for use in any
known operating environment. They
are also fitted with GORE™ protec­
tive venting technology that gets rid
of any accumulated moisture.
All the materials used help protect
against the effects of physical impact,
UV radiation and working environ­
ments in which grease, oil and chem-
icals may be present.
Data about the settings for each valve
are automatically stored in the unit’s
own memory. This important informa-
tion is therefore fully protected against
the effects of any power failure­.
Safe and rugged
Alfa Laval control and indicator units
have well-proven features designed
to ensure maximum safety during
production by making sure that each
valve is doing exactly what it is sup-
posed to – regardless of conditions.
The “no touch” sensor system is less
sensitive to the effects of temperature
and vibration because it is moulded
directly into the valve-top units.
The sensor detects valve stem move­
ment with extremely high accuracy.
This means these units can be set
up with individual tolerance bands for
detecting any deviation in the opening/
closing of the valve plug. This helps
prevent any operating errors that may
result in wasted production.

Broad interface compatibility
Alfa Laval control and indicator units can also provide digital electronic feedback by
relaying sensor data about the exact valve position to a programmable logic controller
(PLC) via a range of different industry-standard configurations. These include traditional
digital interfaces, the relatively simple AS-Interface system and the more advanced
DeviceNet™ fieldbus interface.
By combining bus systems and digital
technologies, Alfa Laval equipment is
compatible with all major PLC digital
input/output cards and gate­ways
for com­mu­ni­cation via other
fieldbus systems. This
makes it easy to combine
different types of control
and indica­tion units and data
communication interfaces to meet
your particular valve control needs
at any given time.
